Filler Types Explained: HA, Calcium, PLLA and PCL
Volume, collagen and how long each one lasts

Not all fillers are the same. Hyaluronic acid filler adds volume straight away and can be dissolved. Other products, such as calcium-based, PLLA and PCL fillers, work more by stimulating your own collagen. Choosing the right type depends on the area and your goal.
Key takeaways
- Hyaluronic acid (HA): instant volume, reversible.
- Calcium hydroxylapatite (CaHA): volume plus collagen, firmer.
- PLLA: gradual collagen build over months.
- PCL: collagen stimulation with smooth volume.
- Choice: depends on area, goal and how long you want it to last.
